WHEELED GUN-CARRIAGE.

Specication of Letters Patent.

Patented July 22, 1919.

Application led May 15, 1917. Serial No. 168,858.

To all whom t may concern:

Be it own that I, EUGNE SCHNEIDER, a citizen of the Republic of France,and residing at Le Creuzot, Sane-et-L0ire, France, have invented a newand useful Improvement in or Relating to Wheeled Gun-Carriages, which isfully set forth in the following specification.

This invention relates to improvements in -wheeled gun carriages adaptedto slide on the lwheeled laxle for the purpose of training.

These improvements consist essentially in guiding the gun carriage uponthe axle by means of a box composed oi two elements capable of slidingvertically relativel to each other, without relative longitu inaldisplacement; one element of the said box is carried by the carriage andthe other by the axle, and metal or other springs are interposed betweenthe said elements of the box.

By this means the body of the carriage is mounted elastically on theaxle, and also in such a manner as not to interfere in any way with thefreedom of slidin of the entire gun carriage along the whee ed axle.

The mechanism for eecting the sliding :of the carriage along the axlemay be carried wholly by that element of the box that slides directly onthe axle. In a modification, the said mechanism may be carried in partby that element of the box that slides directly on the axle, and in partby the carriage and that element of the box that is fixed to thecarriage. In that arrangement, the two parts of the mechanism areconnected together by a telescopic spring device whose elements arejointed by means of Cardan joints to those parts of the mechanism thatare to be connected to one another.

The manner in which this invention is to be performed will now bemorevparticu-y Figs. to 8 illustrate a second practical construction ofapparatus;

Fig. l is a vertical section;

Fig. 5 is a horizontal section on the line V-Y of Fig. 4;;

Fig. 6 is a vertical longitudinal section on the line VI-VI of Fig. 4;

Fig. 7 is a cross section on the line VII- VII of Fig. 6;

Fig. 8 is a part section on the line VIII- VIII of Fig. l.

n In these various ligures A is the gun carriage proper, constructed soas to be capable of sliding along the wheeled axle C. According to thisinvention, the guiding of the carriage A on the axle, in its slidingmovement along the latter, is effected by means of a box composed of twoelements B, B1, extending one inside the other in such" a manner thatneither can have any longitudinal movement relatively to the other. 4butis capable of sliding vertically one in-l side the other. Between thesetwo box cle,y A

ments there are arranged springs D which may be of metal or othenwise.

In the constructional example shown in Figs. l to 3, the mechanism foreilecting the sliding of the carriage along the axle is carried whollyby the box element B1, excepting of course the part which serves as abearing or abutment on the axle. In the example shown, this partconsists of a nut c. In this nut works the screw E journaled in the boxelement B1, and having iixed on one of its ends a pinion F connected bywheel gear G-H-I to pinion J fixed on a shaft K. This shaft K, aslikewise the axles g, L, z' of the wheels, G, H, I, are carried by thebox element B1 The axle 71 is formed in the prolongation of the axle It.

In actuating the shaft K by means of one or other of the hand wheels 7c,cl mounted on its ends, the screw E is rotated, and consequently causedto move longitudinally in the nut c which is fixed to the axle C.

The longitudinal movement of the screw E and oit' the box element B1causes the external box element B and consequently also the carriage Ato move longitudinally.

In the constructional example shown in Figs. 4 to 8, the box element B1that slides directly along the axle, carries projecting guide claws b1(Figs. Ll--5) for the ribs b formed on the box element B that is fixedto the carriage A. This mutual `guide( device ZJ-b1-b1 prevents alllongitudinal displacement of the two box elements relatively tol eachother. AOne part of the mechanism for effecting the Sliding of thecarriage along the axle is carried by the box .element 'B15 another partof the mechanism is carriedaby ythe carriage A and the box element Bfixed tothe latter.

The part that serves to provide a bearing or abutment of the mechanismupon the axle is in this case lconstitu-ted yby a yrack c. That part ofthe mechanism that is carried by the box element B1 comprises a pinion Lwhich yengages with the rack c and has its axle Z journa'led in the saidboxelement B1. The axle Zicarries .also a helical pinion M which engageswith a1 worm N fixed on the shaft n journaled likewise in the boxelement B1.

The shaft n carries further, `on each of its ends a beveled l inion N1enO'aOinU with 7 b C D a pinion O whose axle 0 is journaled like theshaft n and the axle Z in the box element B1.

The axle o carries further, theelement P of a cardan joint PP1 the otherelement P1`Aof which is carried by one of the short shafts Q1 of atelescopic device Q1-Q.

l The short shaft Q1 has a key g1 slidable in a slotg in the short shaftQ. A spring R bears at its ends respectively against the two shafts Q1and Q. The short shaft Q carries fat ,its other end, the element S1 of aCardan joint S-S1 the other element S of which lis 4carried by the axles journaled in a riage sliding along a wheeled axle, wherein theguidance of the gun carriage in its sliding movement along .the wheeledaxle is effected by means of a box composed of two lelements carriedrespectively by the O'un carriage and the axle, and capable of sli ingvertically in relation to each other without relative displacement'along the axle; metal lor other springs being arranged between the saidtwo elements.

2. An apparatus, as claimed in claim l, wherein :the mechanism forsliding the gun carriage along the axle is carried wholly by thatelement of the 4box that slides directly on the axle.

ln testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
